“…Simulation results showed that the hybrid MPC approach recovered 8% of the comfort performance [109]. Simulation on an active suspension system with preview control and a feedforward controller with skyhook logic (to measure the ride comfort of the vehicle over a bump) showed the enhancement of ride comfort is higher using an active suspension control system coupled with skyhook feedback control logic [110].…”

Automotive suspension systems provide passenger safety, ride comfort and vehicle handling in passenger and commercial vehicles. Through extensive research in the last couple of decades coupled with the recent advancements in technology, the improvement in vehicle handling and ride comfort have been significant by using various control strategies in semi-active and fully active suspension systems. Despite a significant number of articles available on the enhancement and improvement of vehicle suspension systems, there is certainly a lack of knowledge on various control strategies and algorithmic techniques used in the vehicle suspension system. Thereby, to address the gap, this review consecutively attempts to comprehensively explore the various research work conducted on the various control strategies used in vehicle suspension systems.

When the vehicle moves on the road, many external factors affect the vehicle. These effects can cause oscillation and instability for the vehicle. The oscillation of the vehicle directly affects the safety and comfort of passengers. The suspension system is used to control and extinguish these oscillations. However, the conventional passive suspension system is unable to fully meet the vehicle’s requirements for stability and comfort. To improve these problems, these are much modern suspension system models that have been used in the vehicle to replace the passive suspension system. The modern suspension systems are used as the air suspension system, semiactive suspension system, and active suspension system. These systems which are controlled automatically by the controller were established based on the control methods. There are a lot of control methods which are used to control the operation of the active suspension system. These methods have their advantages and disadvantages. Almost, conventional control methods such as PID, LQR, or SMC are commonly used. However, they do not provide optimal efficiency in improving a vehicle’s oscillation. Therefore, it is necessary to establish a novel solution for the active suspension system control to improve the vehicle’s oscillation. In this paper, the method of using the double-integrated controller is proposed to solve the above problem. The double-integrated controller consists of two hydraulic actuators which are controlled completely separately. This is a completely novel and original method that can provide positive effects. This research focuses on establishing, simulating, and evaluating the novel control method (the double-integrated control) for the active suspension system. The results of the research have shown that when the vehicle is equipped with the active suspension system which is controlled by the double-integrated controller, the maximum values of displacement and acceleration of the sprung mass are significantly reduced. They reach only 6.25% and 9.10% (case 1) and 6.00% and 6.12% (case 2) compared to the conventional passive suspension system. Besides, its average values which are calculated by RMS are only about 3.91% and 4.67% (case 1) and 4.48% and 4.77% (case 2) compared to the above case. Therefore, the comfort and stability of the vehicle have been improved. This paper provides new concepts and knowledge about the double-integrated control method which will become the trend to be used in the next time for the systems of the vehicle. In the future, experimental procedures also need to be conducted to be able to more accurately evaluate the results of this research.

“…Besides, many other intelligent control methods are also used such as: H control (Rizvi et al, 2018), robust control (Kaleemullah et al, 2019;, adaptive control (Soleymani et al, 2012;, fuzzy control (Lin et al, 2009;Lin et al, 2019;Palanisamy and Karuppan, 2016;Turkkan and Yagiz, 2013;Sun et al, 2013), network control (Fu et al, 2017;Youness and Lobusov, 2019;Liu et al, 2019), etc. Also, integrated controllers with high performance were introduced Lee et al, 2020;Williams and Haddad, 1997;Soh et al, 2018;Elmadany, 2012;Xiao et al, 2009;Sam et al, 2007). In general, the control methods for the active suspension system are very effective.…”

When the vehicle moves, the bump on the road surface is the main factor affecting the vehicle's stability. It produces non-cyclic oscillations and causes a feeling of discomfort and fatigue for passengers. The suspension system of the vehicle is used to regulate and reduce these negative effects. In order to improve vehicle stability and comfort, the active suspension is used to replace the conventional passive suspension system. There are many methods to control the suspension system, each with its advantages and disadvantages. This article focuses on the introduction and establishment of the sliding mode controller for the active suspension system. The results of the study show that when the vehicle is equipped with an active suspension system that is controlled by a sliding mode controller, the values of displacement and acceleration of the sprung mass are significantly reduced. Therefore, the vehicle's stability and comfort are also greatly improved. Besides, the sliding mode controller is very stable to the change of the impact factors. However, this method is more difficult and complex than the use of conventional linear methods.
